6. IMPLEMENTATION PHASE OF A MODIFICATION OR UTILIZATIONPROJECTGENERAL6.1. This section covers fabrication, installation and commissioning stages of theimplementation phase of the approved modification or utilization project. Not allrecommendations are relevant for some projects, for example in cases where the project onlyinvolves changes to procedures.6.2. Irregularities encountered during a particular stage should be dealt with immediately,rather than at a subsequent stage.6.3. Nevertheless, if a stage places a constraint or a requirement on a subsequent stage,procedures to ensure that such constraints/requirements are satisfied should be in place.FABRICATION6.4. For the fabrication stage of the project, measures should be established for thecontrolled procurement of materials, for the controlled development, revision and use ofdocuments and drawings, for the controlled processing of materials, and for the inspection ofsuch activities.6.5. New components or existing ones that have to be modified are generally fabricated ormodified by suppliers in accordance with the detailed specifications that have beenestablished during the design phase. Before selecting a supplier, the project manager shouldensure that the supplier has gained the necessary experience for the work and is aware of allparticular constraints of the project, including management system criteria (see para. 5.20).Preliminary visits to the supplier are generally indispensable.6.6. The project manager should also ensure that the involved suppliers have an adequatemanagement system.6.7. During fabrication, technical and quality audits should be conducted in order to checkand handle all aspects, such as deviations from specifications, quality control and deadlines.INSTALLATION OF THE UTILIZATION OR MODIFICATION PROJECT6.8. Measures should be established for the control of the installation of equipment, andany potential hazards e.g. radiation, chemical, and industrial, should be taken intoconsideration.28
6.9. The installation of the experiment or the modification should not commence until allapprovals has been obtained and before the relevant staff involved in the installation has beentrained satisfactorily.6.10. The schedule for the installation of the experiment or for the modification should beprepared in consultation with the reactor manager to ensure that the reactor is placed in a safestate before commencing the activity.Management6.11. The management of the installation stage of the project should cover at least thefollowing:– Clear identification of all responsibilities, including those related to the managementsystem procedures and radiological protection.– Frequent progress/information meetings with all (technical, operational and healthphysics) staff involved in or affected by the implementation.– Clear procedures with respect to the control (reporting, assessment and disposition) ofdeviations from approved methods and specifications or from the expected behaviour.– Measurement and registration of all characteristics of the system as built; this isrequired for updating relevant technical documents and procedures.– Training and provision of information to internal and external staff with respect to theimplementation scenario, methods, safety aspects, safe working practices.– Contingencies in the project plans to accommodate unforeseen events and operationaldeviations which may require a revision of the working practices and the projectplanning.Safety aspects6.12. The designer should develop a safety evaluation of the installation process, whichshould be based on a detailed installation plan, describing activities, methods, identification ofhazards, temporary provisions and the technical or administrative measures or precautions,which should be implemented to minimize the risk during the installation activities wherenecessary detailed.29
